Android 4.4 KitKat: review of all the new features

The ever-funny Google went crazy with the naming of the new incremental Android 4.4 update. The next letter of the alphabet after the "J" in 4.3 Jelly Bean is "K", so Key Lime Pie was long bandied about for an Android 4.4 nickname, but alas.

Seemingly at the last minute, the folks at Mountain View went and partnered with an actual confectionery producer, and a giant one like Nestlé at that, to name the latest version of Android after one of their most famous deserts, and that's how Android 4.4 KitKat was born.

We can talk long and winded about the marketing synergies for both companies that will result from grabbing a KitKat bar from the counter, with a little green robot munching on the wrapper, but it's time for the new features of Android 4.4 KitKat Google just announced together with its latest Nexus 5 handset. There are a bunch of them, and we know how everyone is impatient to see what they'll be getting for free from El Goog when the 4.4 update hits their phones and tablets, so here's a quick roundup in the slideshow below.

It's a phone, right? RIGHT? That's why we are starting it off with a completely new dialer system in the Peope app that automatically suggests the people you are most likely to call, which can come in very handy when you are in a hurry. Not only that, but the new Caller ID from Google matches phone numbers that dial you with businesses it pulls automagically from Google's vast database of addresses and contact numbers, even if you don't have the contact stored in the phonebook.

There are millions of Android devices out there that don't even have 1 GB of RAM, which seems to be the bare minimum with Android smartphones these days. The streamlined Android 4.4 KitKat default apps and launcher address these 512 MB warriors, letting them take advantage of the new features, for which we are sure their owners will be eternally grateful, and hope their makers will take notice. We also have optimized multitasking and improved touch responsiveness, for the best performing Android version ever.

There's another hidden agenda here, too - optimizing Android further to run on lowly hardware is prepping it for the assault of wearable devices like smart watches we are expecting from everyone now, including Google.

The cyan Holo industrial interface color scheme is now replaced with a white/gray setup that is less distinguishable, but simpler and more minimalistic, which has been Google's aim all along to bring down that resource usage. The default iconography is different now, too, with a flatter design, and we have a new boot animation as well, as well as an improved lock screen with a camera shortcut.

Google is introducing pseudo always-on voice search with KitKat, and a new way to get to Google Now. We say pseudo, because you can activate voice search from your homescreen with a key phrase without even touching the display, but it works only on the Nexus 5 for now. Otherwise you can swipe from your homescreen to get to Google Now, and speak the phrase "OK, Google" there.

These will evoke the personal assistant, which Google says is now 25% more accurate, and talks back. Moreover, new cards for local shopping and attractions, as well as buying movie tickets via Fandango on the spot are on their way.

Google's Hangouts IM service now lets you send text messaged and MMS as well, from within its interface, and threads all your conversations with a contact, regardless of the channel they went through. You can also post GIFs, and use the Autoawesome feature to brighten your video chat sessions with Hangouts.

Navigation can get out of the way now in any app that is best used full screen, like when you are reading, for example. Swiping from the edge of the display will bring back the status bar and navigation buttons. We praised a similar feature in Huawei's Emotion UI, and obviously Google has come to the conclusion how useful it can be to pop and hide distractions anywhere you like in Android.

A picture is worth a thousand words, that's why the default Android keyboard now gets those colorful Japanese symbols dubbed Emoji, for when you are too bothered to type "cactus".

The camera app features a photo editor that contains a number of filters that are built-in. And you can even turn your own favorite combination of settings into a preset that you can use to quickly have your pictures come out the way you want them. The editor won't ruin your original picture, so if you don't like the way it came out, you can try again.

You can open and save files and images from/to your phone or tablet, Google Drive and a plethora of other storage services, whatever picks your fancy, utilising the new storage framework with staples like the Gallery or QuickOffice. There is a list of recent files everywhere to pick up where you left off quicker.

You can print photos, documents, and web pages from your phone or tablet wirelessly now. Naturally, Google Cloud Print is supported, and from the other gear, HP ePrint machines will work with this out of the box. We'd wager to bet other printer makers will quickly add their wireless printing apps to the Google Play Store, too.

Finally we get a way to easily browse between the stock and installed launchers, or "homescreen replacements", as Google calls it. Just go to Settings>Home, and you'll switch from Apex to Nova to your stock KitKat homescreen in a jiffy.

Android 4.4 adds support for screen recording and provides a screen recording utility that lets you capture video as you use the device and store it as an MP4 file. You can record at any device-supported resolution and bitrate you want, and the output retains the aspect ratio of the display. To prevent piracy, Google says devs can add a simple code flag which would likely black out the content area or halt recording. Check it out at the 5m10s break.

Android KitKat collects sensor logs and delivers them in batches for processing, thus dramatically reducing battery consumption even on devices without dedicated sensors for motion or speech processing. In addition, the Nexus 5 includes step detectors for pedometer and other fitness apps to take advantage of, and Google is working with chipset manufacturers to include those in their future gear as well.

Android 4.4 adds platform support for audio tunneling to a digital signal processor (DSP) in the device chipset itself. Audio decoding and output effects are off-loaded to the DSP, conserving battery. With audio tunneling, Nexus 5 offers a total off-network audio playback time of up to 60 hours, an increase of over 50% over non-tunneled audio. Google is working with chipset partners to make it available on more devices soon.

Android 4.4 support for two new Bluetooth profiles to let apps support a broader range of low-power and media interactions. Bluetooth HID gives apps a low-latency link with low-power peripheral devices such as mice, joysticks, and keyboards. Bluetooth MAP lets your apps exchange messages with a nearby device, for example an automotive terminal.

Android 4.4 also introduces platform support for built-in IR blasters, along with a new API and system service that let you create apps to take advantage them.Using the new API, you can build apps that let users remotely control nearby TVs, tuners, switches, and other electronic devices. The API lets your app check whether the phone or tablet has an infrared emitter, query it's carrier frequencies, and then send infrared signals.

Because the API is standard across Android devices running Android 4.4 or higher, your app can support the broadest possible range of vendors without writing custom integration code.

One of the optimizations Android 4.4 KitKat includes to be able to run on devices with as little as 512 MB of RAM, is granting devs or users a way to take a closer look at a specific app's memory usage in isolation, by just tapping the app in the new on-device memory status service. For each app, they can now see a summary of the memory consumed and the percentage of the collection interval that the app has been running, as well as the average and maximum usage over the collection period, and below the app's services and the percentage of time they've been running.

Analyzing these in Process Stats allows for identifying the memory hogs easily, isolating gaps, and optimizing for the next generation of affordable low-RAM Android phones and tablets which should run KitKat without a hitch.

Google has thought not only about the functionality, but the looks with Android 4.4 KitKat, too. Developers can now use new window styles and themes to request translucent system UI, including both the status bar and navigation bar. To ensure the legibility of navigation bar buttons or status bar information, subtle gradients are shown behind the system bars. "A typical use-case would be an app that needs to show through to a wallpaper," says Google.

I actually think it is possible, if you make a backup of the netflix apk today, (read: before they Update) Then you can install the old version of netflix on your nexus 5 and then it will be possible to record netflix...

The Linux kernel used by Android already supports AArch64 (aka ARMv8) but it's just not enabled because there is not need to. Just a few core runtimes will require recompiling but Apps would work as usual since Dalvik core (bytecode) is independent of word length.

Wow. This was a bigger update than I initially expected. This is starting to sway me from getting a Retina iPad mini. Maybe I'll go check out a Nexus 7 in store again in a couple weeks when it gets the 4.4 update...

You were actually considered that $399 ipad mini? Seriously? I laughed so hard when I first heard that price.
Good for you for willing try the Nexus 7 but you can have two of them for the price of 1 iPad mini. And it's a better tablet anyway (in my opinion). It's no contest.

The problem is 16:9 tablets are awkward to hold vertically, while the 4:3 ratio isnt optimal I think is the best form factor for a tablet and I had a nexus tablet, and still getting the nexus 5, but prefer the ipad form factor.

I really just wanted to try iOS 7 personally, something new to me. I didn't feel like getting an iPhone 5S because I wanted a slightly larger screen and I felt like I couldn't part with some of Android's features, but I was willing to try the iPad mini, once it got a Retina display and A7 of course. As long as I had Android as my smartphone OS, I didn't feel the need to get the Nexus 7, but now that I see KitKat, I'm starting to have second thoughts.

You and me two. I don't know what have those things do but I know I can't do them now. I aspecially like the little emotion thingys on the keyboard, I know I can't do that now but that sound like a useful feature. My only problem with the other stuff is I'm still not sure how that messaging intergration gonna work. Also, anybody know if I can get the keyboard on my phone now until I buy a new phone?

One thing seems evident - Android is now head and shoulders above iOS, and should absolutely trump it even in the performance /stability.
We're looking at thoroughly improved kernel here.
iOS 7, otoh, is having tons of issues and is simply a second grade OS in comparison.
